OneStim™
The OneStim™ Cardiac Stimulator is an electrical stimulus generator for diagnostic cardiac stimulation during electrophysiological testing of the human heart.

OneStim-DUO™
The OneStim-DUO™ is a robust platform that provides two selectable CRM and MEP operating modes in one portable cardiac stimulator:
MEP (EP) Mode: A 4 channel intracardiac EP stimulator/mini-recorder for basic EP with up to 50V stimulation and portable EP applications.
CRM (PACE) Mode: An all-in-one mode for LBB/CSP pacing, including 12-lead ECG, pacing, COI, impedance and RWPT measurements.
